We present a search for a new high-mass resonance decaying to $\mu^+\mu^- + X $, using a matrix-element-based likelihood and a simultaneous measurement of the mass and rate. We see no significant excess; the best fit point is $M_{Z'} = 199$ GeV, with 1.3\% signal fraction, consistent with the standard model. We place limits on a set of $Z'$ models, including $M > 1071$ GeV for a standard-model-like $Z'$.
